I tried to restore my computer system to correct a problem I was having and the tech that I was talking to had me try to load the restore discs that came with my computer. That didn't work and I lost the operating system in my computer and had to load the operating system disc that came with my computer to get it to work again. Well originally I had 40 gb on my hard drive. Now I only have 16.
When I follow this path: Start>Control Panel>Admin. Tools> Computer management> Disk Management I find on the hard drive I have 16.1 gb being used and 21.24 gb are unallocated.
How do I get all of the original Hard drive Back??
